Background: Men who have sex with men (MSM) are at increased risk of acquiring hepatitis A and B and vaccination is recommended. Although acute hepatitis A and B rates are at historic lows, these diseases remain significant public health problems among MSM.

Methods: National surveillance data were analyzed to evaluate trends among MSM using cases of symptomatic acute hepatitis A and B reported to state health departments during 1990-2002. Data included demographic and risk characteristics.

Results: Hepatitis A incidence declined since 1995 and in 2002 was the lowest yet recorded (2.9/100,000 population). However, rates in adult (>20 years) male are substantially higher than those in female (4.3 versus 2.1/100,000 respectively, p <.001). The adult male to female rate ratio was 2.1 in 2002 versus 1.3 in 1992. The proportion of male cases attributed to MSM increased from 8% in 1992 to 29% in 2002. Hepatitis B incidence declined since the late 1980s and in 2002 is at a record low (2.5/100,000). However, rates in adult male are substantially higher than in females (4.3 versus 2.3/100,000 respectively, p <.001). The adult male to female rate ratio was 1.9 in 2002 versus 1.5 in 1992. The proportion of male cases attributed to MSM increased from 18% in 1992 to 26% in 2002.

Conclusions: Hepatitis A and B rates are declining nationwide, but increasing among adult men with an increasing proportion of cases in MSM. These data indicate a need to build and strengthen vaccination efforts for adults at high risk.
